IMPLEMENTATION
Call this tool
Connect a user's Notion account once, then configure and run Create Comment from your backend or agent.
import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "notion-create-comment",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
notion: { authProvisionId: "apn_xxxxxxx" },
pageId: "Page ID or URL",
discussionId: "Discussion ID",
},
})
console.log(result)curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \
-H "Content-Type: application/json" \
-H "X-PD-Environment: production" \
-H "Authorization: Bearer {access_token}" \
-d '{

"configured_props": {
"notion": { "authProvisionId": "apn_xxxxxxx" },

}'// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(
new URL("https://remote.mcp.pipedream.net/v3"),
{
requestInit: {
headers: {
Authorization: `Bearer ${accessToken}`,

},
},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
name: "notion-create-comment",
arguments: {
pageId: "Page ID or URL",
discussionId: "Discussion ID",
},
})SCHEMA
